Activity Schema
A standard data model to make reusable analyses possible
Single source of truth
You don’t have to search through many tables or spend hours figuring out why numbers don’t match. All your company data is in one data model making it easy to find and always accurate.
Simple traceability
No web of dependencies. All reporting and analyses tables depend on a single table in your warehouse (modeled using an Activity Schema).
Minimal maintenance
Changes to BI tables (adding new columns, updating logic, etc.) can be done in a few clicks without adding any complexity to the definition.
Reinvented joins
Bridging data across systems doesn’t require custom engineering. You can bridge data from disparate systems easily and without defining foreign keys.
The activity schema standard
Narrator adheres to the activity schema standard for all of its data modeling.
To learn more please see the full specification.
Activity Schema
How it's built
The Activity Schema is a data model designed for column-oriented data warehouses
Step 1
Define customer actions (activities) using simple SQL transformations
Logic is simple and easy to understand (~25 lines of code)
Activities are the building blocks that are used to assemble tables
All company definitions are managed in one place
Each activity follows the standard Activity Schema format. For more information on the 11 columns that make up each activity check out our ‎docs.

Activity Schema
How it's used
A table modeled using an Activity Schema can be reassembled to generate any table for BI, reporting, and analysis
Narrator’s core innovation is that every data table can be constructed using a combination of activities and relationships between those activities.
Activity

Using the Narrator platform, quickly assemble any table to:
Answer any question
Materialize any table for reporting or BI
Build the dataset for your next analytics or data science project
Activity Schema
Open Standard
The Activity Schema is an open-source data modeling standard
Narrator follows the activity schema specification and is proud to sponsor its development. Please visit the official site for documentation and more information.
"Narrator provides value by consolidating and organizing our activity data in such a way that's meaningful and flexible so that we can quickly create a dataset to answer relevant business questions."
